Increase -XX:MaxPermSize and number of JVMs for oacore in R12

Increase -XX:MaxPermSize and number of JVMs for oacore

1. Shutdown Applications

2. Take Database and Application backup before start activity.

3. Take a backup of the $CONTEXT_FILE.

4. Edit the $CONTEXT_FILE and change the -XX:MaxPermSize parameter on the line below

FROM: 

<oacore_jvm_start_options oa_var="s_oacore_jvm_start_options">-server -verbose:gc 
-Xmx512M -Xms512M -XX:MaxPermSize=160M -XX:NewRatio=2  -XX:+PrintGCTimeStamps -XX:+UseTLAB

5. Verify that s_oacore_nprocs is set to 2 on the $CONTEXT_FILE

cat $CONTEXT_FILE|grep s_oacore_nprocs

6. Take a backup of the $INST_TOP/ora/10.1.3/opmn/conf/opmn.xml file.

7. Edit the $INST_TOP/ora/10.1.3/opmn/conf/opmn.xml file and search for the process-type 
id="oacore" and update the following lines or settings under it:
